To all whom may comem Be it known that I, Jon I. -Fins, a citi- Zen 01 the United Slnios, residing in Brooklvn. county of Kings, aincl ff-l fgl'e of New Torlz, have invented ii new kind useful In:- proveinent in Mael'iines for lwlalz ing Eilgings. of which the following is :1. (lfESCllPl'lOH.

To this end strip of tape. or braid. or other mar row material of the character desired, is usually held on a reel and located in some convenient posilion upon :1 stnml or "table iports the sewingmachine, and after being nosed lhrmigh the machine is usually allowed to fall in mass into receptacle, or. to a sltnncl, or 0*; ierwise pile up in rear of ihe machine. This results in the mass becoming entangled, massed, and very much impaired for commercial purposes. Moreover. the clmraeler of the work has ren- (lered it difficult to wind the some upon a. reel antonmlioally because of the heavy rib produced thereon along the senior, or body thereof,- snoll rib, when the binding zip plied, usually lying along the edge of the garment or fabric. My invention, now to be described. sncce sinlly lakes care of the ma.- lorial before.

On the outer end of the spindle 11, a spring 15, is coiled, which bears against the adjacent disk of the reel 10, and creates pressure thereon to provide the necessary tension or friction upon the tape 16. Pressure of the spring 15, may

be regulated by the collar 17 held in place by the thumb-screw 18, tapped through said collar and engaging the spindle 11. This means combined with the collar 19 and 19, on opposite sides of the reel 10, the collar 19 being suitably fixed to spindle 11, holds the latter in anupright position and prevents wabbling of thel; same on the spindle. The bracket 12,. slidest? longitudinally in the socket 20, of? a bracket-piece 21, fixed to the bed-plate 1, of'the machine, said bracket beprovide the end abutments which engage the opposite ends of the bracket 23, the latter being also extended at 28, providing an abutment against which the bridge-piece 29, of the collar may engage to prevent axial movement of the rod 24. At its inner end the rod 24, is provided with a clamp-collar ,30, through the bottom of which is extended an; aperture in which freely slides a belt shifting arm 31, held or set in proper position by means of the screws 32. The construction shown permits the belt-shifting arm to be properly positioned with reference to the pulleys so as to engage the driving belt and shift the same from the one to the other of said pulleys. The outer end of said rod 24, slides freely in the bracket 21, and is provided, between said bracket. 21, and the bracket 23, but nearer the former, Withan adjustable collar 33. The bracket 21, has a short shaft 34,, freely journaled therein so as to rock, and the inner end of said shaft is provided with a cam-finger 35, adjustable upon said shaft by means of a setscrew- 36, which holds said finger in proper operative position, as hereinafter described. The outer end of the rock-shaft 34. has fixed thereto an arm 37, to the upper end of which is secured a socket-piece 38, in which is adjustable an angular arni 39. The adjustment is secured by any suitable means, such as a set-screw passing through the socketpiece 38, and engaging the stem 40, of the arm 39, while. the socket-piece 38, is held in any suitable position by means of the binding screw-38 which drives the body of the socket-piece 38, against the arm 37, and securely clamps the same to said arm. The extension 41 of the arm 39, is positioned so as to extend substantially parallel with thefront edge of the cloth-plate, slightly below the latter, and between the same and the reel 10. This places the extension 41, in position to cause the tape, which passes thereunder from the reel 10, to describe two angles, one at the extension and the other at the cloth-plate, in passing to the stitchforming mechanism.

()n the cloth-plate of the machine,-Figs. 1, 8 and 4,is supported a lever 42, the pivot thereof being indicated by 43, which extends through the lever. screws into the cloth-plate, and is provided between said plate and the lever with a collar or washer 44, on which the lever rests, turns, and by which it is prevented from engaging the cloth-plate. The rear end of the lever 42,

has pivotally connected thereto, the socketpiece 45, in the socket of which is adjustably connected a rod 46, having its front end suitably. extended beyond the cloth-plate and then bent down below the latter at 47, and then backwardly at 48, toward the extension 41, and into position to engage the same as hereinafter described. Therod 46.

is adjustable in the socket 45, by means of a set-screw 49, and said rod is provided beyond the socket with an adjustable collar 50, which engages and regulates' the pressure of a spring 51, coiled about said rod and having its other end held by a fixed stop 52, secured to the cloth-plate and through which said rod slides. The free end of the lever 42, is extended at 53,.to provide the lower jaw of the tape or strip guide, the upper jaw of which is formed of a spring plate 54, adjustably secured to the lower aw 53, by means of the set-screws 55. The dis-' tance between the two jaws 53 and 54, may be fixed and regulated in any suitable manner, as by providing a shoulder 56. on the lower jaw, or by inserting washers between .5

the two jaws encircling the adjusting screws. As before stated the upper jaw 54, is a spring and is sufficiently light to render it sensitive to variations'in the thickness of the work passing under the same; that is to say, after the jaw 54 'has been set to allow a given thicknessibf work to pass there under and between it and the lower jaw 53, with the requisite amount of friction, or tension, shouldthe thickness .ofthe, work increase for any reason, the spring-jaw 54, would yield vertically and not impede the travel or feed of the work nor objectionably affect the guide. The jaw '54, for the purpose, may be made of ajlight, steel spring, or may be made thin at the point 54, so

ill

' elem-pl es to provide therequisite amount of elas ticity, and allow the jaw to yield from a point beyond the adjacent adjusting-screw 55. The rib of the work passes through the guide along approximately the line Fig. i.

The cloth-plate of the machine, between its front edge and the resser-toot 57, is

provided with an adjustable st1.ip-guide,or

The upper plate 60, is adjustable on the lower plate 58, and the two are held in relative position and securely fastened to the cloth-plate by means of the clamping-screw 62, passing; through the slots of the said plates 68, end 58,v and into the cloth-plate. In rear of the presser-toot and also in rear of the guide Isa--54 is provided a holdingplete 63, suitably fixed to the cloth-plate by clemping screw 64, and extending across the path oi. "revel of the tape 16, and forming between it and the cloth-plate a passage for said Said plate is thus located for the purpose of ediztug' and holding the tape ine p .il-l with the surface of the i.

and passing through the guide end also for relieving the stitching ism of direct strain resulting from the W -31 1i. of the reel 76 and its supporting parts;- het is to say, the tape, after lem ing' the stitching position, passes under the holding-plate which keeps the tape down is surface of the work-plate and moves the lifting strain upon. the heel of the .presser -foot and drag; upon the needle, as well upon the guide 53-43%. This is important, since, if the reel-frame and reel were to impose their weight and directly upon the needle and foot, substantielly at ency would the needle a the stitching position, the tendbe for the work to drag upon nd strain and break the same, as

well as lift the foot from the work and release its hold on toe work. As will hereinutter appear guide 5 l-fil is 111 etlect a feeler which eno'e 'es the stitch or rib made I a a: J: a I

by the stitch, upon the suriace 0t thestrlp or braid, and this feeler is so adjusted to become very Sensible to the presence or absence of said stitch, or rib, upon the tape or braid. For the above reason, said guide Will be hereinafter referred to as e .t'eeler :Eleonred to the rear of the bed-plate. 1, etthe machine, is the usual feed-rocking treme 65, the shaft "66, of which is jourleeving the stitching posi na-led in the bracket 67. Loosely j ournaled upon said shaft 66. is the tapereceiving reel-frame 68, by means of the tubular sleeves or bushings 89. One end of the shaft 66, is headed at 70, and is provided with a. fixed collar 7l. located in a split in the outer bearing 6%. This provides a means by which theshaiit (36, when moved or adjusted longitudinally in its hearings will carry with it the frame (58 and thus properly position the receiving recl relatively to the line of travel of the tape. The shaft (36, may be securelvhcld in place by means of the tlnunb-screw 72. In the upper end of the frame 68, a spindle 73. is journeled, carrying at one end a fixed belt pulley T -i, around which runs a belt 75, passing around and frictionally engaging the driving Shaft"? At its other end the spindie .73, is provided with the receiving-reel 76, substantiall 7 reel 10, and said spindle is provided with a spring 77, a collar 78, and Re thumb-screw 79, substantially identical with, and for the same purpose as, the similar elenu-nts which cooperate with the reel 10.

Attention is directed to F 1 oi? the drawings wherein the position of the frame 68, is clearly portrayed its weio'ht and its pivotal bearing causing the same to have a tendency to tell away from the clotlnplate of the machine and create tension on the driving hand 75, and friction of the latter on the driving-shaft This position of the frame also causes the reel 76, to take up the slack between itself and the holdingplate 63.

It will he observed that the belt-shifting rod 24, is normally hold in an inoperative position by means of the spring 33-. cured to the collar 33, and the bracket 21, viz. with the belt runnim on the loose puls ley; and that the cam ringer is normally held tromcontact with the collar 33. by means of: the spring 35, connected to the rm 3'7, and to the bracket 21, this position of the arm 27, also holding the angular arm 39, out of contact with the tripping-mechanism which is actuated by the feeler.

The operation of my invention is as follows: It should be primarily understood that the stitch-forming mechanismproduces a line of stitching upon both sides of the work. that on top being of ordinary, straight-ahead stitches, and that on the bottom being in the nature of a rib. such as produced by a single or a double chainstitch. Such a stitch is diagrammatically illustrated in Fig. 5, merely to portray graphically the difference in thickness between the tape 16, before the stitch 16*, is applied and after the same has been applied. This diflerence is the feature upon which the tripping of stopping mechanism de- Ponds, and the absence of the stitching is identical with the saidof the cloth-plate, between the strip-guides to the stitch-forming mechanism, thence through the jaws of the feeder, under the arm 63, and on to the receiving reel 76. The machine is started by pushing the rod 24, to the right and causing the belt to be shifted from the loose to the fast pulley. This op eration; distends the spring 33*. Then the arm 37, is pressed outwardly toward the operator causing the finger 35, to engage the side of the collar 33, and hold the rod tape 16, and

34 in itsoperative position, with the spring 33 distended. Thus moving the arm 37, distends the spring 35", the strength of which, however, is less than that of the spring 33*. The strength of the spring 33*, is such that the finger 35, will be thus held in engagement with the collar notwithstanding the tension of the spring 35*, the tension of the the tension of the spring 51, on the tripping-rod 46. The machine is now operating and the friction of its drivingshaft 2, drives the band 75, which rotates the pulley 74. and turns the receiving-reel 76, thus winding the tape 16, on the latter. The instant the stitching, applied to the tape 16, engages the jaws of the feeler, the latter is caused to move to substantially the dotted line position shown in Fig. 3, the friction of the line of stitching, or the rib thereof, being suflicient to carry said feeler to said dotted line position and constantly maintain the same in such position during the application of the stitch and so long as such stitch is present on the tape. This operation compresses the spring 51. and forces the rod 46, away from the extension 41, of the angular arm 39. If the thread of the machine should break, or for any reason the stitch should not be applied to the tape,as by the skipping of stitches,--the absence of the stitch would be immediately detected by the feeler and the latter would instantly assume the solid line position of Fig. 3, by reason of the expansion of the spring 51, and which would cause the end 48, of the rod 46, to forcibly engage the extension 41, of the arm 39, and remove the finger 35. from engagement with the collar 33. and allow the spring 33*. to draw the rod 24, longitudinally in its bearings and carry the belt-shifting arm 31, across the pulleys and. carry the drivingbelt from the fixed to the loose pulley, thus stopping the machine. This same belt-shifting operation would be performed in the event of the tape 16, being exhausted from the reel 10, because the parts are so sensitive and the adjustments and tensions are so nicely regulated that the moment the tape leaves the reel, when exhausted, the diflerence in the tension on the arm 39, is materially felt, and the spring 35*, will instantly free the finger 35, from engagement with the side of the collar 33, thus allowing the driving belt to be shifted from the fixed to the loose p'ulley as previously stated.

It will be; obvious that as the tape is wound upon the reel 7 6, the tension on the tape will graillu'ally increase by reason of the bulk,- of"inater'ial: on the reel. This would ordinarily be objectionable because of the constant driving of the reel by the main-shaft 2; but, this objection is overcome by reason of the particular driving connection between the shaft 2, and the driving pulley 74, shown and described. As the material-on the reel 7 6, increases in bulk or diameter, the tension on the tape is naturally increased, resulting in drawing the reel 76, toward the machine and the stitching point, this being permittedby the loose, pivotal connection of the frame 68,

on the bed-plate of the machine. Being thus drawn toward the machine, the driving-band7 5, is instantly loosened, decreasing thereby the driving power of the shaft 2, upon said band 75, .andalso decreasing the speed with which wound upon the reel.

sion increases on the tape, during the process of winding the same upon the reel 76, the speed with which the reel 76, is driven is decreased, the one counterbalancing the other, or compensating each other, and pro- Hence, as the tenthe tape is being viding a practically automatic reeling derequiring no attention from the 'op The same change in tension is the length of feed:

vice, erator. caused by a variation in that is to say. if, during the machine, the feed should be changed,- as from sixteen stitches to eight stitches to the inch,the tension onthe reel would be instantly decreased and the speed of the reel increased. This will be clear when itthe operation of is considered that, with eight stitches to' the inch, the feed is rapid, and material is supplied to the reel more rapidly, decreasing tension. and allowing the reel to fall back from the cloth-plate and create greater friction between the driving-shaft and the driving band. A reverse action takesplace when the number of stitches to the inch is increased. Hence, in all cases, the speed with which the receiving-reel is driven is commensurate'with, and in proportion to, the tension on the work, and the variation 15 automatic.

It will thus be seen that I have provided the Work;

a machine for producing edgings which is absolutely automatic in its operation and requires no attention, after once being started, from the operator. It will also be seen that l have provided a mechanism whereby the machine may be automatically stopped upon occurrence of either of two events, viz., the absence of the stitching on the tape or the delivery reel.

ing the same through the machine. Ob-

VlOUSlj, when this has been done the tape is loose between the reel and the stitching point, and the machine is started again by merely placing the finger upon the tape-reel and Winding the same back upon the reel until the same is drawn taut, the extension e1, being drawn back so as to depress the arm 37,:1nd lift the finger 35, into proper position for engagement with the side of the collar 33, as previously explained. in stantly the machine is started and t1 stitching engages the t'eeler, the latter will be carried into the dotted line position of Fig. 3, as previously described. WV hen the connected ends of the tape have reached a position between the arm 62$, and the reel 76, said ends may be disconnected, the full reel removed from its spindle, an empty reel substituted, and the end of the new tape properly secured to the new reel, which tape is immediately wound upon the re ceiving reel and the operation of the 1nachine continues as before.
